PMT HIGH VOLTAGE POWER SUPPLY

  • Max Voltage: 2 to 5kV
  • Max Current: 1 to 2mA

Integrated power supply for preamplifier

EP series is high performance high voltage power supply for for Photomultiplier Tube (PMT), electron multiplier application.
Ultra compact size of just 8.35 inches/212 mm width integrated high voltage power supply and power supply for preamplifier ±15 V and ±5 V. The ultra low ripple noise of as low as 15 mVp-p (high voltage output part) is suitable for PMT and various other applications. In addition, various digital control is also possible by selecting the -LGob option.

FEATURES AND BENEFITS

  • Integrated power supplies for the preamplifier (±15 V, ±5 V output)
  • Low ripple 15 mVp-p (2 kV models high voltage output part)
  • Ultra-compact design of the best in its class
  • Large and noticeable 4-digit digital meter
  • Full protections

Options

-LGob

Optical Interface port
This option changes the standard interfaces to built-in optical interface port. By combining this option with an adapter for optical connection (sold separately), communication between the control device and the power supply can be controlled in an isolated state. Be sure to select this option when using the product in the following environments.

  • -LGob: Optical interface + optical cable 2 meters
  • -LGob(Fc5): Optical interface + optical cable 5 meters
  • -LGob(Fc10): Optical interface + optical cable 10 meters
  • -LGob(Fc20): Optical interface + optical cable 20 meters
  • -LGob(Fc40): Optical interface + optical cable 40 meters

Select the optional optical interface port (-LGob) when using this DC power supply under the following conditions.

  • Noisy environments such as factories
    (example: when motors or coils are used near loads or power sources).
  • If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
  • When there is a possibility of arcing or output short-circuit.

Accessories

Optical isolation adapter

To use the optical interface, you need to prepare an optical interface adapter separately. The following interface adapters are available according to your controller port.

  • CO-E32: LAN to optical interface adapter
  • USB-OPT: USB to optical interface adapter
  • CO-OPT2-9: RS-232C (9 pin) to optical interface adapter
  • CO-OPT2-25: RS-232C (25 pin) to optical interface adapter
  • CO-OPT4-25: RS-485 (25 pin) to optical interface adapter
  • CO-G32: GPIB to optical interface adapter (Discontinued in December 2028)
